Fig. 12 is a perspective view of the product of the machine.

Referring to Figs. 1, 2 and 3, 20 indicates a base upon which are uprights supporting bearings '22 in which is journaled a shaft 24 from which movement of the power driven parts of the machine is derived. Upon the shaft 24 is a worm gear 26 driven by a worm 28 which is operated by a motor 30 supported jaws 88,

in a standard 32 arising from the base 20.

Pivoted upon stationary trunnions 34 are the forward ends of a pair of arms 36 upon Pivoted at which is mounted a support 38. 40 upon the support 38 riers 42 which are geared together. as shown at 44, to cause them to move equally and oppositely about their pivots 40. The support 38 is provided with which pass clamping screws 48 threaded into the respective carriers 42, providing for securing the carriers in any angular position to which they may be adjusted.

Tucking blades 50 are mounted upon the carriers 42, being fixed in position by retainmg blocks 52' secured by screws 54. The

I et g-e portions 56 (see Fig. 6) of the tucking blades 50 are thin while their base portions, in the region indicated by 58, are relatively thick. As shown, the additional thickness is secured by the provision of an additionalpiece ofmetal 60 but this is solely for convenience in manufacture, and forthe purposes of the invention the parts 56 and 60.

should be regarded as integral, since they j center line of which is indicated by the for a time, and finally elevated to an expansion spring 92 (Fig. 1) the are tucking blade cararcuate slots 46 through are rigidly secured together and together form the tucking blade. In other words, the tucking blade might as well be formed of a single piece of material.

The inner portion of each of the carriers 42 forms, at 62, an abutment beside the tucking blade 50, said abutment being adapted to be engaged by a face of a channeled heel 64 at one side of the channel 66 which the tucking blade is to enter. The illustrated machine is designed to operate upon a heel having a. channel in its breast face parallel and adj a-- cent to each breast corner and it will be seen that the two upwardly facing tucking blades 50, with their adjacent abutments 62, afford means for positioning such a heel when the carriers 42 are properly adjusted upon the support 38 to cause the blades to conform to the channels in the heel.

Rigid with the arms 36 and extending rearwardly from the trunnions 34 is a cam lever 68 (see Figs. 1, 3 and 11) carrying a cam roll 70 which is freely rotatable upon a stud 72 which is eccentrically mounted in the lever 68 and held in adjusted position by a nut 7 4.

The roll 70 engages in a closed cam 76 the heavy dot'and dash line 7 8 in Fig. 1. The cam 7 6 is secured to the shaft 24 and rotates therewith andis of such shape that the arms 36 are first lowered, held in lowered position for a time, then raised part way, held in this position their initial position.

After a heel 64 has been positioned upon thetucking blades 50 and their abutments 62 it is seized by a clamp or holder comprising a pair of arms 80, 82 movable about a pivot 84 secured in stationary upright brackets 86. The arms 80, 82 are provided with roughened 90 arranged to engage the attaching the outer face respectively of the held separated by ends of which are seated in pockets in the two arms.

For the purpose of closing the clamping jaws upon the heel there is provided a cam 94, pivoted at 96 in ears 98 which are rigid with the arm 82. Secured to the cam 94 is a handle 100 by which the clamp'may be closed manually.

Co-operating with the cam 94 is a button 102 having a threaded stem 104 engaging a nut 106 which is splined in a housing 108 secured firmly to the clamp arm 80. A stiff spring 110 contain-ed in the housing 108 is backed up by an adjustable screw 112 and bears against the nut 106, tending to force the latter against a stop plate 114 secured to the housing.

The tension upon the spring 110 is adjusted by means of the screw 112 to secure face and heel 64 and are normally the clamping pressure desired, and the but- 1 tion: shown.in:Fig. 1, Wherein-. a.;stop:pirn116.-

to whichthey would adhere, making the sub sequent tucking 'operati on dilficult. I 'Duringthe retraction of the shear blades 150, or immediately thereafter; the tucking blades 501are partially raised-to position such that the breast face of the heel, when it is again swung outward, will just; clear. them .easily. The tucking. blades jremain in this position while the heel-clamp swings outward avrod 188 (Fig. 1):=which 1nay-.be actuated by...-to its; initial position-.and stops.

During the outward transfer of the heel from trimming position to initial or tucking position the deflected edge'portions of the cover, which are convergent because of the taper of the heel, engage the. upper edges of the similarly convergent tuckingblades 50,. first assin outward between the blades and then being further deflected inwardly of the heel by passing over the blades, asshown in Fig. 10.

When the heel has come to rest the deflected, trimmed edge portions of the cover 18% rest upon the edges of the tucking blades and the channels 66 are exactly above the blades. Finally the support 38 is elevated to its initial position, causing the blades 50 to lay the trimmed edge portions of the heel cover upon the breast face of the heel between the channels 66 and the corners and tuck the cover into the channels, whereupon the machine stops. The clamp 80, 82 is now opened, releasing the heel, which is removed, and the machine is ready for the reception of the next heel to be operated upon.

The dimensions and conformation of the tucking tool 50, with its thin edge and relatively thick base portion, are determined by the dimensions of the channel inthe heel to be operated upon and the thickness of the covering material to be used. The thickness of the base portion of the tucking tool approximates the difference between the width of the channel, and the thickness of the covering material and the width of the thin edge portion of the tool is at least as great as thedifierence between the depth and the width of the channel. Thus, while it is impossible for the edge portion of the cover material to be pinched or caught between the thick base port on of the tucking tool and the side of the channel in the heel, provided the cover has been trimmed to the proper width as shown in Fig. 6, in the early part of the tucking operation, yet when the thick base portion of the tool enters the channel in the heel the edge of the cover issmoothed and pressed firmly against the wall of the channel to which it will adhere, leaving adequate space in the channel for the subsequent tucking in of the edges of breast cover.

Variation of the width of the edge portion of the cover left projecting past the breast face of the heel after the trimming operation, to suit the requirements of the heels being dealt'with, is secured by adjustment of the normally stationary cutting blades 136, the further toward the center of the machine they are set the greater being the projection of the trimmed edge portion of the cover.
